Application filed November To all 707201 72 it may "concern:

Be it known: that l, STnrHEN Hansen, a citizen of the United States, residing at lVashington, inthe District of Coluinhia, have invented certain new and useful Improvements in Line-JustificationJudicating Mechanism, of which the following is aspecification, v

This invention relates to machines for prestrips for tllltOl'llfltlC type casting-and similar machines, and has particular reference to improvements in the line justification indi.- cating mechanism. i

The improvement is particularly adapted for use with the justification space indicating mechanism shown in Patent No. 1,288,- 623, which patent shows certain improvements upon such mechanism, shown in Patent No. til-405. i IirPatent No. 1,283,623, a lever is automatically swung upon its pivot, and operates a valve, and this valve will then discontinue the operation of the justification indieating mechanism. This lever is swung upon its pivot when the upwardly moving bar, which carries the pointer cooperating with the justiiication chart, has reached a predetermined position. The bar reaches this position after a predetermined number oft justiiication spaces are placed in a line, and should the operator again touch the justilieation spa-cc lrey, the further move I want of the bar will swing the lever and shift the valve, as above stated.

Should the operator-,jbetore the predefication spaces from being recorded in the line, he inoves a rodforwardly or toward him, and the movement of thisorod raises a bar which swings the lever upon its pivot, to shift the valve, in a similar manner as occurs when the justilication rack has reached the upper predetermined position. This construction is well known and possesses marked advantages.

However, it frequently happens, during the setting off one line, that the operator will move the rod forwardly, to prevent "further 7; 922. Serial no. 599,612.

justiiicationspaces from being recorded in wardly to the normal position, so that the ustihcation space indicatlng mechanism will be restored to the operative condition. As a result o:t this, the justification space indicating mechanism will not properly func tron in setting the succeeding line. paring or composing controllers or record In accordance with my pose to provide a device maticallj move under or valve shitting lever, or the extension thereof, when the lever is swung upon its pivot, as the rod is moved forwardly. The rod may now be returned to the inner or rear position as soon as it has been moved forwardly for elevating the bar which swings the lever. By this means, there will he no tendency for the operator to forget to return thero'd, with the results which flow from such neglect. When the complete line has been set, and the several parts of the machine reset, as by the pressing of the resetting key, the pawl or pawls which engage the teeth or the j ustification rack are thrown out of engagement with such rack, to perini tot the same hein-g reset, and these pawls are employed to operate the element engaging with or beneath the lever to operate the valve, whereby such element releases the lever which will return to its normal position, allowing the valve to be restored to its normal condition, and hence the justification space indicating mechanism will be properly restored. In other words, as soon as the line set, the justiiication space indi cating mechanism will be restored, just asit the rod had remained in the forward position, and was forced rearwardly to the normal position, at the end of the line, as is now the practice.

invention, I prowhlch Wlll autoengage with the In the accompanying drawings forming or attachment, showing the holding element in the released position, and,

Figure 3 is an edge elevation of the device, with associated elements in elevation.

The same reference characters employed in Figures 3 and 1 of Patent No. 1,283,623, will be used, in describing the parts which are old and shown in this patent. 85 is the space counting bar, operating in a guide 85'. 86 and 87 are the lifting and holding pawls, acting on the teeth a of the bar 85 and controlled by the motor 90. 198 is a valve, controlling through the shift valve, the transference of the signal from the punches for the justifying space to those of the nonjustifying space. 201 is the valve operating lever aetin upon the valve 198.

Upon the inner end of the lever 201 is pivoted at 11 a three arm lever, one arm 13 of which forms a linger piece or the like, while the arm is adapted to rest on the lever 201 and the arm 16 projects into position to cooperate with the shoulder 1? on the space bar 85 and to be acted on by the upper end ot the manually controlled bar 10. The three arm lever forms a releasable extension of the lever 201, forming a proper connection between the lever 201 and the bar 85, and allowing of the ready removal of the bar 85, as clearly set forth in Patent No. 1,283,623.

The vertically movable bar 10 is adapted when elevated to engage the arm 16 and through it move the lever 201 and the valve 198. This bar 10 is manually controlled through the medium of a knob or finger piece or rod 11 mounted to slide in bearings in the frame and provided with a cam or inclined face 12 for cooperation with the lower end of the bar 10.

I he elements so far described are old and well known and are set forth particularly in Eigures 3 and 4: of Patent No. 1,283,623.

attention is also called to the trip 92, which is shown in Figure 3 of Patent No. 1,283,623 but is not therein numbered. Attention is also called to Patent No. 944,405, above referred to, particularly to Figure 19 thereof. This trip 92 is clearly shown in Figure 19 and is arranged to engage with pins 9 1-, carried by the pawls 86 and 87. As is clearly set forth in Patent No. 94 1,4105, when a line has been completed, the various parts of the machine are reset, bythe strile ing of a resetting key, and this action causes the trip 92 to move toward the pawls S6 and ST, whereb 1 these pawls disengage the teeth a. and are swung outwardly away from these teeth, so that the bar 85 may descend or be reset. This outward movement of the pawls is ordinarily called kicking-off of the pawls.

My deviceor attachment embodies an inverted L-shaped support or plate B, which the guide 85 by screws C. The plate 13 has pivotal connection at D with a holding element E. This holding element projects upwardly beyond the pivot in the form of an extension F, having connection with a spring G secured to an extension H of the plate B. The lower end of the holding element E is provided with a laterally extending linger I, which is adapted to rest in engagement with the side of the arm 16. The element E is also provided with an extension or tail J, disposed generally at a right angle to the linger I. The extension J is located across the pawls 86 and 87, and is so arranged that when these pawls are thrown outwardly to release the rack 85, such pawls will engage the extension J, and swing the holding member E outwardly upon its pivot.

In the operation of the machine, the rack 85 is moved upwardly, as explained in Patents Nos. 1,283,623 and 944,405, whereby the justification space indicating mechanism is operated. This action is caused by the operation of the justification space keys, the air passing to the motor 90 each time a justi'fication space hey is actuated by the operator, and also to the motors of the justification space punches. The motor 90 acting on the arm 91 raises the lifting pawl 86, which, ongaging the teeth of the justilication space mounting bar 85, raises the latter through one division. Should the operator after the predetermined number of justification spaces that are to be placed in a line is reached, again touch the justiiication space key, the bar 85 in rising will lift the arm 15 through the engagement of the shoulder 17 and this will cause the lever 201 to turn on its pivot cl and operate the valve 198. The valve 198 will operate to allow air to pass to shift the valve 20 soas to close the communication of the space signal keys with the space signal punch motors, and transfer the conin'lunication to the punches of an ordi nary space. The motor 90 receives its inotive fluid through one of the justilicatiou punch motors, so that when the power is shut off from this motor by the operation of the valve 20, no further nrovement of the bar 85 would take place.

Vith the bar 85 thus elevated, and the outer end of the lever 201 elevated, the holding element E is automatically shifted toward the lever 201, and its linger 1 will slide under the lever 201; The spring (1* will hold the element E in this position. until the parts are reset, by the pressing of a resetting key, at which time pawls 86 and 87 are swung outwardly and engage the extension J and shift the element E outwardly so that the extension I is withdrawn from beneath the lever 201", which is now reset.

It is thus seen that under these conditions,

is rigidly secured to the prose cof the holding element E does not inter are with or alter the normal operati on of the nrcc h-anisn'i.

hould the operator, before the predetermined number of justification spaces has been reached, desire to prevent further just-ification spaces laom. being recorded in the line, he moves therod ll. forwardly in the direction of the arrow, and the operation will take place as clearly described in Patent No. 1,283,623. Instead of allowing the rod 11 to remain in the forward or withdrawn position until the line is completed, the operator at once returns the rod 11 to the inner or rear position as soon as it has been shifted to j the outer position, thuseliminating the liability of the operator forgetting that the rod 11 is in the outer position, and allowing it to remain in this position, during the setting of the next line. As soon as the rod 11 is thus shifted to the outer position, the bar 10 arises, and by engaging the arm 16, swings the lever 201"" upon its pivot, as explained. The instant that this leveris swung upon its pivot, the linger I slips under the lever and hence holds or locks it against a return movement. Therefore, when the rod ll is pushed to the inner or rear position, immediately, described, the lever 201. is held in the shifted position, just as if the rod 11 remained in the open or forward position. The lever 201 is held in this shifted position until the end of the line is reached, at which time a resetting key is struck, and the parts of the machine are reset, including the movement of the trip 92 for throwing the pawls 86 and 87 outwardly. When these pawls move outwardly, to reset. the bar 85, then engage the extension J and the element E disengages or releases the lever 201, which is free to return to its normal position.

It is to be understood that the form of my invention herewith same, and that various changes in the shape, size, and arrangement of pz'irts maybe rcsorted to without departing from the spirit of my invention, or the scope of the sub joined claims.
